What each level generates

Grade 6 doubles and halves — the exact skill behind each difficulty setting, straight from the generator.

  1. Level 1Double it
  2. Level 2Halve it
  3. Level 3Undo a double or a half

Grade levels follow the progression common to most English-language curricula — not one specific national curriculum. Every level shows exactly what it generates, so you can check the fit with your own program. See the full scope & sequence →

Each one generates a different kind of question, with its own three levels and answer key.

Frequently asked questions

▸What should Grade 6 mental maths include?

Square numbers, percents of amounts, and multiplication, division and subtraction with larger numbers — plus the ability to chain two of them together. Six sheets cover exactly that ground, each with three levels of its own.

▸How do you work out a percentage of a number mentally?

Start from 10% by dividing by ten, then build: double it for 20%, halve it for 5%, add the pieces for 35% or 75%. Every amount on these sheets is chosen so the answer lands on a whole number.

▸Which square numbers should a Grade 6 student know?

The squares to 15 by heart is a common target, with 16 to 20 close behind. Level 1 of the Squares sheet generates squares from 2 to 24 and level 2 goes from 25 to 45, so you can push recall well past the times tables.

▸Are these sheets suitable as a daily starter?

Yes — that is what a high question count and a shuffle button are for. Print thirty questions for a five-minute starter, press Shuffle for tomorrow's set at the same skill and level, and print the answer key for instant marking.
